This document describes the features and characteristics of a smart two-channel high-side power switch called PROFET® Preliminary BTS 725 L1, including overload protection, current limitation, short-circuit protection, thermal shutdown, overvoltage protection, etc. It is suitable for 12V DC grounded loads, especially resistive and lamp loads. The product can replace electromechanical relays and discrete circuits.
The BTS 725 L1 is a two‑channel high‑side power switch designed for 12 V DC grounded loads. It integrates a vertical N‑channel power FET with a charge pump and CMOS‑compatible input, offering built‑in diagnostic feedback and extensive protection functions.
Key features include over‑voltage, under‑voltage, overload, short‑circuit, reverse‑battery, and ESD protection, as well as open‑load detection and an open‑drain diagnostic output. The device is supplied in a standard P‑DSO‑20‑9 package and can replace electromechanical relays in many applications.
